He then traveled to many countries including Spain, Japan and Russia to study various drama styles and methods.
He admired Spain"s Federico García Lorca and spent few weeks experiencing Lorca productions such as Yerma.
In Japan he studied traditional kabuki drama and was involved in a popular production: The Father. Returning to Sri Lanka in 1961, Galappatty resumed his theatre work.
Abandonning the operatic form modelled on Charles Silva and Sarachhandra crystallization of the Nadagam, he branched out on a new line which tried to fuse the inner-directed acting style that he had imbibed in Broadway with the non-naturalistic native tradition. In 1962, he produced a milestone in Sri Lankan theatre, "Muduputtu" (Sons of the Seas), showing that the traditional stylistic theatre could be blended very effectively with western realistic technique.
Following this he was at the forefront of Sri Lankan theatre and his productions launchd the careers of many talented actors.
